NEW YORK (Reuters) - Three former London-based traders are expected to go to trial on Wednesday in federal court in Manhattan on charges they conspired to rig prices in the roughly $5 trillion foreign exchange market.

Lawyers are expected to make opening statements in the case once a jury has been chosen. U.S. prosecutors announced the charges in January 2017.
Ashton was Barclays' global head of spot currency trading, Ramchandani was Citigroup's head of G-10 spot currency trading, and Usher had a similar role at JPMorgan, according to court filings by prosecutors.
The case followed worldwide investigations that resulted in about $10 billion in fines for several large banks, and the firing of dozens of traders.
Several others have been charged in the U.S. probe, including Mark Johnson, a former head of foreign exchange cash trading at HSBC Holdings Plc
Barclays, Citigroup, JPMorgan, BNP Paribas SA
Britain's Serious Fraud Office decided in March 2016 to close its own criminal probe, saying it lacked a "realistic prospect" of obtaining convictions.
